I DEPROVEMENT IN TUBES FOR OILERS.

- To all whom it may coneem:

Be it known that I, FREDERICK J. SEYMOUR, of Meriden, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Tubes for Oilers; and I do-hereby declare the following, whentaken-in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specifi cation, and represent, in-- Figure 1, a side view of the-tube complete;

Figure 2, a vertical central section ofthe same; and in 1 Figures :5, 4, and 5, the various operations to produce the tube complete.

, This invention relates to an improvement in tubes for oilers, such .as are commonly used for ejecting oil for various mechanical purposes.

Heretofore these tubes have been formed from sheetmetal, rolled up, and the two edges brazed together,

and a screw attached to the base; or have been formed from cast-metal, and bored out;- either of which involves no inconsiderable expense of time.

The object of my invention is to produce an article equally as good, and at a comparatively trifling cost.

To this end, my invention consists in constructing the tube by drawing or spinning out a cylinder of metal, and forming the screw and bead in one and the same p ece.

To enable others'to construct my improvement, I 'will proceedto describe the sam'efas illustrated in the accompanying drawings.

I take, first, a cylinder of metal,fas seen in fig. 4, of about the diameter required for the base of the tube, and of a length to afford sufiieient metal for the spinning out of the tube. This cylinder is placed upon a conical mandrel, and, by any known device, is spunout and drawn down, as denoted in fig. 3.

The cylinder may be wholly open at both. ends, or partially so, or entirely closed,'like a cartridge-shell. I prefer, however, that the cylinder be open alike at both ends.

Thus drawn down, the base of the tube is enlarged, as at a, fig. 5, by inward pressure or otherwise.

Then, in suitable dies, the enlargement A is struck down close, as at d, figs. 1 and 2, which forms the bead by means of which the tube is turned on to the cup. Below the bead d, a thread is out to fit the cup, as seen in fig. 1, and the tube is complete, and from a single piece of metal, without seam or joint.

This manner ofspinning conical tubes is applicable to many purposes other than oiler-tubes, and, for such purposes, is alike valuable and important, as heretofore such tubes have been formed as I have first described for oiler-tubes. My invention, therefore, while designed especially foroiler-tubes, is not confined to such purpose.

I do not wish to be understood as claiming a solid metal tube.

Having fully described my invention,

What I claim as new and useful. and desire to secure by Letters Patent, is

As an article of manufacture, the conical metal tube, formed by drawing or spinning from a cylinder, without scam or joint,'substantia1ly in the manner herein set forth.
